In the surveillance video from the hotel entrance, Zhang Ping, Han Bin and Li Hui could see that Xiao Kai dragged his suitcase out of the hotel, walked a distance along the road, and disappeared from the video surveillance of the hotel. Then, from a nearby barbecue store, where they copied the CCTV, Xiao Kai's figure reappeared, and they saw him dragging the heavy suitcase and putting it on an electric tricycle. The electric tricycle was covered by an awning. Once he entered the electric tricycle, he and the baggage could be unseen. Once the suspect's transportation is found, the next task will be easy.
